TANK-CAR HEATER.

Chicago, in the county of Cook and State of Illinois,.ha\'e invented certain new and useful `Improvements in Tank-Car Heaters, of which the following is a specification.

My invention relates to apparatus for heating the 'contents of a tank car in order, for example, to give it sufficient fluidity so that ,it may be readily discharged from the car; apparatus of this sort being of particular 'utility in connection with cars used for the transportation of crude oil or.` other liquid or semi-liquid, the fluidity of which is decreased -by low temperature, in which case it is desirable to apply heat to the oil beforeit is discharged in order to facilitate such discharge. v-

The principal object of the invention is to provide a heating systeni'for a ca'r of this type which will be compact, so as to take up as little room vas possible in the car; which will be so constructed as not to interfere, to any appreciable extent, with the complete discharge of material froin the ear, or with the cleaning of the car 1; and of which the parts will be so related that the apparatus will withstand the internal stresses set up when the heating pipes expand or contract. In this latter connection it will be understood that the cargo of the tank car is not heated in transit. The heat is lapplied ,after the car has reached its des` tination. For this reason, it' the car has been traveling for soiiie time through a region of `low temperature the introduction of the steam, orother heating medium. into theheating coils, causes a rapid' and unequal expansion of they metal with which it is brought into contact.

The invention consists iii the novel and improved constructions, arrangements and devices to be hereinafter described and claimed 'for carrying outthe above stated objects and such other incidental objects as will appear from the following description.

The invention is illustrated, in certain preferred einbodinients, in the accompanying drawings wherein Figure 1 is a sectional plan of va tank car fitted with the heating apparatus of iny invention.

Fig. 2 is a fragmentary vertical :sectional view of the same.
